Authorities track suspects in attempted vehicle theft in Mill Valley

A San Francisco woman was arrested and a San Francisco man was being sought after what police described as an interrupted vehicle theft in Mill Valley on Friday.

The incident occurred at about 4:15 p.m. at a construction company on Miller Avenue, where police received a report that a man was trying to steal his supervisor's vehicle, said Mill Valley police Sgt. Mike Lane.

When the witness confronted the suspect and a woman with him, the suspect allegedly threatened to cut the witness with a knife, Lane said.

The suspects then fled across the street, got on a motorcycle, put on their helmets and raced south toward Tamalpais Junction. After a widespread search by Mill Valley police, sheriff's deputies, the California Highway Patrol and state parks rangers, the suspected motorcycle was found on Marion Avenue.

Authorities found the woman suspect nearby and arrested her. She was identified as Laura Close, 32.

Authorities were still looking for the male suspect, whom they identified as Adam Pilger, 32, as of Saturday evening. Lane said Pilger was being sought on suspicion of attempted vehicle theft, criminal threats, brandishing a weapon, conspiracy and evading police.
